Reaktionsschritte

To a solution of 2.06 g (10.0 mmol) of 3,5-di-tert-butylphenol in 10 mL of trifluoroacetic acid was added 1.6 g (11.0 mmol) of N-(1-isopropoxyethyl)acetamide and the resulting mixture was stirred overnight at room temperature. The reaction mixture was concentrated in vacuo, and the residue was partitioned between EtOAc and saturated aqueous NaHCO3. The aqueous layers were separated and then extracted with EtOAc. The organic layers were combined, dried (Na2SO4), filtered and evaporated in vacuo. The product was purified on a silica gel flash chromatography column eluted with 0-25% EtOAc in CH2Cl2. Evaporation of the purified fraction and drying in vacuo afforded the title compound.
